Where is the vehicle identification number on a semi truck cab?

The vehicle identification number (VIN) on a semi-truck cab is typically located on the driver's side of the dashboard, near the windshield. It can also be found on a metal plate or sticker on the driver's side door frame. Additionally, the VIN may be listed on the vehicle's registration and insurance documents. Always check the manufacturer's specifications for exact locations, as they can vary by make and model.
